  • Effects of Pulmonary Rehabilitation on Exercise Capacity and Quality of Life in Patients with Stable Chronic Obstructive Pulmonary Disease

    ObjectiveTo investigate the effects of pulmonary rehabilitation on the exercise capacity and quality of life in patients with stable chronic obstructive pulmonary disease (COPD) for a optimal strategy for pulmonary rehabilitation. MethodsOne hundred and six patients with COPD in stable stage were divided into group B (n=37), group C (n=36), and group D(n=33) based on GOLD 2011.Each group of patients were randomly subdivided into a control group(usual care), a pulmonary rehabilitation strategy group 1 (breathing training), and a pulmonary rehabilitation strategy group 2 (breathing training and exercise training), and they were intervened for 24 weeks.Pulmonary function(FEV1%pred), COPD Assessment Test (CAT), modified British Medical Research Council dyspnea scale(mMRC), BODE index and 6-minute walking distance(6MWD) were compared before and after intervention. ResultsAfter pulmonary rehabilitation intervening for 24 weeks, in group B and group C, pulmonary rehabilitation strategy group 2 showed the best effect, CAT, mMRC, BODE index, and 6MWD were proved significantly different before and after pulmonary rehabilitation (P < 0.05).In group D, all indexes had no significant difference between pulmonary rehabilitation strategy group 1 and group 2 before and after pulmonary rehabilitation (P > 0.05), but they were better than those of the control group.Correlation analysis showed that CAT score had significant correlation with FEV1 % pred, mMRC, BODE index and 6MWD (P < 0.01). ConclusionPatients with different subgroup of COPD based on GOLD 2011 may take different pulmonary rehabilitation strategies to achieve the optimal effect.
